Skylight Freerange 2: Gachduine

Or, above all else, this: Skylight Freerange 2 is definitely not the worst game of 2016. That, uh, honour was clinched long ago by Energy Hook. But it's very, very, very close between the two games. The only reason SF2 doesn't come away with the title is because Energy Hook was a broken, unfinished mess, whereas this is, despite all appearances, a finished game. But it's still absolutely horrifying in every way, and unless you're a glutton for punishment, you'll want to avoid this one at all costs.
